    The history of pond management in Czechoslovakia is reviewed briefly. Czechoslovakia had the leading position in Europe in the 15th and 16th century, it nationalized the ponds after World War I and introduced the carp-and duck system after World War II. The current Czechoslovak production data are given. There are 52 200ha of ponds with an annual output of 16 000t of marketable fish (of this, 15 200t are carp) and 11 000t of waterfowl (ducks, geese). The specific features of pond management, including intensification measures, are not oriented to simple maximization of output through intensive fattening of the fish, but aimed at an ecologically balanced management of the development of natural food in the ponds by polyculture. Emphasis is placed on the rearing of supplemental fishes (mainly tench, silver carp, and whitefish), optimum determination of pond stock densities, monitoring and controlling quality parameters by computer methods, and use of cereals as feeds in combination with natural food. Production results are achieved under advantageous economic conditions and characterized by superb quality of the fish meat which is due to the large proportion of natural food in the diet of the fish. Intensification practices are supported by veterinary care organized by the State Veterinary Service. Fisheries research is an organic part of the State Fishery Concern as a monopoly producer of marketable fish. Thus the problems investigated by researchers are very closely associated with fish farming practice.
